Ren Woxing Vs Yue Buqun at the end of SPW
Let suppose Yue Buqun wasn't killed by Yilin at the end of SPW. If YBQ and RWX were having a death match, who would win? RWX has higher internal energy and better technique but YBQ has better speed and healthier. According to SPW 1984 with Chow Yun Fat as LHC, YBQ had a death match with RWX. RWX was winning the fight but got fire deviation and YBQ used the opportunity to kill him.
If I have to bet, I would bet YBQ would win but it would be a close match.
